S?ECIFIGATION forming part of Letters Patent No. 745,497, dated December 1, 1903. 1 Application filed August 15, 1902. Renewed April 9,1903. Serial No. 151,921. (No model.)

To all whom it may concern: 7 casing near the bottom of the compartment 31 Be it known that I, HIBAM Q.

In the side of the through the opening 9.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction, mode of operation, and advantages of my improved filter will be readily apparent without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A filter comprising a casing, a partition dividing said casing into two compartments, filtering material in said compartments, perforated channel-pipes affording communication between said compartments, hoods or shields covering said perforated channelpipes, an inlet to one of said compartments, and an outlet to the other of said compartments, substantially as specified.

2. A filter comprising a casing, a vertical partition dividing said easing into two compartments, filtering material in said compartments, perforated pipesaftording communication between the lower portions of said compartments, an inlet to one of said compartments, an outlet to the other of said compartments and an overflow connection between the upper portions of said compartments affording communication between the said compartments adjacent to the inlet,

whereby during heavy rains the Water will be allowed to pass directly from one compartment to the other without being filtered, substantially as described.

3. A filter comprising a casing partitioned to form two filter-compartments in communication at one end and having an overflow connection at the other end, an inlet-pipe to one of said compartments, and an outlet-pipe in the other of said compartments, the said overflow connection being located adjacent to said inlet-pipe whereby when the water reaches a certain level in the inlet-compartment it will pass to the outlet-compartment without being filtered, substantially as and for the purpose described.

4. A filter comprising a casing partitioned to form an inlet filter-compartment and an outlet filter-compartment, said compartments being in communication at their lower ends, and having an overflow connection at their upper ends, a coarse filtering material in said inlet-compartment, a screen located above said coarse filtering material, a fine filtering material in said outlet-compartment, a washout connection in the lower portion of said inlet-compartment, a removable cover, an inletpipe in said cover commuicating with said inletcompartment, and an outletpipe in said outlet-compartment, substantially as set forth.-

In testimony whereof I have hereunto set myhand in presence of tWo subscribing witnesses.
